Per an idea made by tfabris in the "Reviews" board: I think using the mic to sense "ambience noise levels" and having Empeg auto-adjust the volume would be awesome! It would be a similar effect to speed-sensitive volume, but quite probably much more effective. And it wouldn't need to be too sophisticated. For example, every 1-2 seconds, have the player 'poll' the mic for noise levels and then adjust volume difference accordingly to a preset default level.
